Nitrogen has an atomic mass of 14 and an atomic number of 7 so the number of neutrons must be?
The Atomic Mass of an atom is the total mass of its particles. The atomic number is the number of protons in the atom's nucleus.
To find the number of neutrons in an atom, we take its atomic mass (the total mass of its particles) and subtract its atomic number (the number of protons and electrons in the atom).
A: Lithium has an atomic mass of 7 and an atomic number of 3 so the number of neutrons is equal to 4. (7 - 3 = 4)

What is the atomic mass number A for N with 7n?
The atomic mass number A is the total number of protons and neutrons in an atom's nucleus. For nitrogen (N), the atomic number (number of protons) is 7. If it has 7 neutrons (designated as "7n"), then the atomic mass number A would be 14 (7 protons + 7 neutrons).
Nitrogen has 7 protons and 7 neutrons The atomic mass of nitrogen is?
14 A proton has an atomic mass of approximately 1 AMU. A neutron also has an atomic mass of approximately 1 AMU. For most purposes, the atomic mass of an electron is considered to be negligible. Without knowing the number of protons this atom contains, one cannot calculate the atomic mass of the atom.
How many neutrons does nitrogen -5 have?
Nitrogen-5 (N-5) is an isotope of nitrogen with a mass number of 5. Since nitrogen has an atomic number of 7, indicating it has 7 protons, we can calculate the number of neutrons by subtracting the number of protons from the mass number. Therefore, nitrogen-5 has 5 - 7 = -2 neutrons, which indicates that this isotope is not stable or physically plausible, as it cannot have a negative number of neutrons.
How do you determine neutrons?
take nitrogen as an example it has an atomic number of 7 that determines the number of protons as 7 positive charges so it takes 7 negative charges (electrons) to even it out so you have 7 electrons and protons. then you take the atomic mass which is 14.01 but you can round it to 14. then you take the atomic number and atomic mass and subtract them (14-7=7) so the number of neutrons is 7.
How is the number of neutrons in an atom found?
The number of neutrons in an atom can be found by subtracting the number of protons (which is the atomic number) from the mass number. The mass number is the sum of protons and neutrons in the nucleus of an atom.
What is Nitrogens atomic number and mass and why does it have that?
atomic mass - 14 atomic number - 7 It has that because it has 7 protons (and electrons) = the atomic number. And it also has about 7 neutrons and roughly, the mass number = the number of neutrons+ the number of protons.
How can you find the number of neutrons in the isotope nitrogen-16?
Subtract the number of protons (atomic number) from the mass number 16. The atomic number of nitrogen is 7, therefore its atoms have 7 protons. The number of neutrons in the atoms of the isotope nitrogen-16 is 16 -7 = 9 neutrons.
What is the atomic mass number A for N with 7n?
The atomic mass number A is the total number of protons and neutrons in an atom's nucleus. For nitrogen (N), the atomic number (number of protons) is 7. If it has 7 neutrons (designated as "7n"), then the atomic mass number A would be 14 (7 protons + 7 neutrons).
What is the number of protons and neutrons in N?
The atomic number of nitrogen is 7. So there are 7 protons and 7 electrons. The number of neutrons depends on the isotope. N-14 has 7 neutrons. N-15 has 8 neutrons. Number of neutrons = Mass number - Atomic number.
What is the number of neurons in nitrogen?
Nitrogen is an atomic element and does not have any 'neurons' because neurons are nerve cells.I think you meant 'neutrons' :-Nitrogen has an atomic mass of 14.00674 and an atomic number of 7. As the majority of mass in an atom is in the nucleus and as the atomic number represents the number of protons in the nucleus, the number of neutrons ROUGHLY = the atomic mass minus the atomic number. In other words Nitrogen would have 7 neutrons in its nucleus.The fractional part of the atomic mass is because there are isotopes of nitrogen some with more or less neutrons than 7. In fact there are two stable isotopes of nitrogen: 14N and 15N the most common is 14N (99.634%).
How many neutrons can be found in an atom of nitrogen?
Number of neutrons = Atomic mass of an isotope - Atomic number of the element For the most important natural stable isotope of nitrogen - 14N - the number of neutrons is 7.
What is the atomic number of nitrogen -14?
The atomic number of nitrogen is 7. The atomic number represents the number of protons in the nucleus of an atom. The isotope "nitrogen-14" refers to an atom of nitrogen that has 7 protons and 7 neutrons in its nucleus.
What is the mass number in nitrogen?
Nitrogen is a non metal element. Atomic mass of it is 64.
What is the number of protons electrons and neutrons in n-14?
Nitrogen-14: 7 Protons, 7 Electrons, 7 Neutrons To work this out in the future for other elements: Protons = Atomic Number Electrons = Atomic Number Neutrons = Atomic Mass - Atomic Number Hope this helps!
What information would be requierd to determine the mass number of nitrogen?
You would need to know how many protons and neutrons are in the nucleus of a particular isotope of nitrogen. The number of protons, which is its atomic number, will always be the same, no matter which isotope is given, but the number of neutrons differs with different isotopes. For example, one isotope of nitrogen has 7 neutrons. To determine its mass number, find nitrogen on the periodic table, and you will see that its atomic number is 7. So this isotope of nitrogen has 7 protons. Now, add the 7 neutrons to the 7 protons, and you get a mass number of 14 for this isotope of nitrogen, which is called nitrogen-14. (Isotopes are named by their mass numbers.) Another isotope of nitrogen has 8 neutrons. Add the 8 neutrons to the 7 protons (atomic number), and you get a mass number of 15 for this isotope of nitrogen, called nitrogen-15.
Nitrogen has 7 protons and 7 neutrons The atomic mass of nitrogen is?
14 A proton has an atomic mass of approximately 1 AMU. A neutron also has an atomic mass of approximately 1 AMU. For most purposes, the atomic mass of an electron is considered to be negligible. Without knowing the number of protons this atom contains, one cannot calculate the atomic mass of the atom.
A radioactive isotope has eight neutrons Write the atomic number and mass number of this radioactive nitrogen as a chemical symbol with a subscript and superscript?
The atomic number of nitrogen is 7. When it is a radioactive isotope you add the number of neutrons to the atomic number (equaling 15). You then write 15 over 7 next to a capital 'N' representing Nitrogen.
